TILE.

SPECIFICATION forming part Of Letters Patent N0. 650,387, dated May 29, 1900.

Application filed March 28, 1899. Serial No. 710,805. (No model.)

To au w'wm t may concern:

Be it known that I, LEOPOLD GNTH, engineer, a subject of the King of Vrtemberg, residing at Friesenhofen in the Allgtn, Kingdom ofNVrtemberg, Germany, have invented new and useful Improvements in Tiles, of which the following is a specification.

The present invention relates to that class of roofing-tiles wherein the adjacent tiles of one layer are joined together by means of one 0r more grooves and projections at one side edge ofthe tile and corresponding projections and grooves at the side edge of the adjacent tile, so that the tiles partly overlap one another, the special purpose of the present invention being to produce a tile which admits of forming a perfectly-close roof smooth on the outside, and at the same time admits of slight changes in the position in consequence of slight changes in the supports, differences in the bedding, and unequal contractions without interfering with the closeness of the joint. The preventing of the entrance of water or snow by its being blown in by the wind and the carrying off of any water that may have formed `by sweating are further points provided for in the present invention.

With these ends in view the invention consists in certain novel features of construction and arrangement and combination of parts hereinafter described, and the essential elements of which are recited in the appended claim.

The annexed drawings illustrate the invention.

Figure l shows a view of a tile seen from above. Fig. 2 is a view from below. Fig. 3

4is a longitudinal section, and Fig. et is a crosssection taken through two tiles lying side by side.

The form of the plan of the tile is that of the common beaver-tail tile. The outer surface possesses no protuberances at all and may be provided with channelsffor guiding the water, between which there are smooth surfaces e e, or be without them, as desired. At both sides there are longitudinal ledges g, one of which has a double lap-joint on the lower surface and the other asimilar joint on the upper surface. These joints consist of or are made up of the groove lo in the upper surface of the lower ledge, closed at the top end, and the outside groove h, while the surface of the tile-ledge which engages with it is constructed correspondingly to make the jointing, as shown.

The under side of the tile is provided with a fastening or holder at the top end, which sits behind the roof-hatten, and below it has one or two ledges i, one of which is formed by a thickened edge of the tile and forms a `weir. These ledges prevent water or snow from being driven in. In the center an angular ledge is provided, which carries od at both sides any water formed by sweating. Owing to this construction it is not necessary to make the tile hollow for the purpose of obtaining the thickness necessary for the jointing. Without endangering the closeness of the joint, these double-beaded joints may have so much play that the tile may shift slightly in any direction. The tile illustrated is such that it may easily be manufactured in a rotary-drum press or any other press for making tiles with overlapping edges in plaster or iron molds.

The tile may be made of cement, clay, or similar material.

Having now particularly described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described article of manufacture consisting in a tile with smooth upper surface, having grooves and projections provided at one side and on a sunk projection at the other side, said tile tted with a transverse projection at the top end of the lower surface for gripping behind the roof-hatten, with a transverse rib near the bottom end of the lower surface and with a rib forming the bottom edge, said two ribs resting tightly on the preceding layer of tiles, to prevent blowing in of wateror snow, an angular rib further provided in the center portion ofthe lower surface serving for carrying off water formed by sweating, substantially as described and shown and for the purposes mentioned.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

LEOPOLD GNO'III.
